The Coalition for Constitutional Reform (CCR) Kenya wants Canadian Mining Company Tiomin Resources Incorporation to discontinue plans for titanium mining in Kwale, Coast Province.
CCR Kenya and its partners say the contract agreement under which Tiomin Resources has been operating is based on the exploitative free entry system.
The pro-reform body says the system is a dominant means through which mineral rights are usually granted to mining companies in most countries.
It gives the miner's the exclusive right to people-owned mineral substances from the surface to unlimited extension downwards.
Consequently, CCR Kenya is calling on the company to initiate a departure process through which they can be justly compensated any fees they paid to landowners.
The pro-reform body says titanium deposits in Kwale should be left to the Kenyans to help local processing industries and not handed over to a private company for export without processing.
CCR Kenya plans to launch a nationwide campaign on Wednesday against Tiomin's mining activities in Kwale.
Signatures are being collected from members for a petition to the government.
